1 Do Now & Announcements Take out HW to be checked Work on Do Now
Half-Life Quiz FRIDAY 12/12

2 Radioisotope: isotope that is radioactive
Isotope: different versions of the same element. They have the same # of protons, different # neutrons Radioisotope: isotope that is radioactive Stability: neutron to proton ratio is 1 (for elements H through K) 1.5 (for elements Ca through Bi) Half Life Time it takes for half of the atoms in a sample to decay

3 Nuclear Energy k0-SDmI 3:38

4 Radioactive Tracers in Medicine
